Question

int a=2; printf("%d", ++a + a++);

Answer 1

int a=2; printf("%d", ++a + a++);

answer is:6

Comments

no the out put will be a garbage value

---

It will be the 7.

The expression is not a legal C expression as the C standard does not specify in what order this needs to be executed, hence the evaluation depends on the compiler itself. Just try the GNU C, Turbo C or Microsoft C and you can see the result differs for the same code.

Hence the answer is: UNDEFINED BEHAVIOUR

---

a = 2
a++ = 3
++a = 3

++a + a++ = 6

answer is 6

yeah answer is 6

Answer 2

'5' will be the answer.

Answer 3

'7' is the answer.

no bro it is 6
printf("%d",++a + a++);
firstly the ++a adds 1 before using a
so the value of a will become 3 and then that value is used.
now it is added to a++,
here the value of a is used first and then increment will happen
so (3 + 3) {To be noted that the value of a is 4 now )
answer is 6
thats it. it is simple bro
even i confused first,then i saw a comment saying its answer is 6 , then i again checked it, thats how i got it right.
byee

Answer 4

6 is the answer

Answer 5

5

++a define a=a+1, So it's value is a=3

a++ define only a+1 but it noe store into a so value of a is 2

so 3+2=5

so final answer is 5

Comments

Sorry to say but you are wrong.
Value of a is 2 at first
For ++a, the value of a is icremented by 1 immediately,so it becomes a=2+1=3
++a=3
So, the new value of a is 3 now
the trickiest part now ---------
therefore, (++a)+(a++) = 3 + 4 = 7
so 7 will be the answer

---

bro you are wrong too
i would agree with the first part
but in the second part ,it is post increment
so the value of a is used first and then the value of a is updated (i mean an increment is made)
SO
(++a) + (a++)=3 + 3
 now the value of a is 4
but the answer for that code is 6.
thank you for the oppurtunity to help you.

Answer 6

output of this is 5

Answer 7

Output for this is 7

a has value 2 the it get incremented as 3 add to the post incremented value 4 then the answer is absolutely 7.

Answer 8

initially pre-increment operation occurs, ++a=3, then substiution of the values takes place,i.e (++a + a++)=(3 + 3) =6 then post increment occurs hence a becomes 7

the ans is 7

Answer 9

ANSWER is 6 because 3+3=6

Answer 10

answer will be 7
